raku - 如何知道我正在运行的 perl6/raku 版本？

Question

尝试-v切换，我得到了鹦鹉 svn 修订版：

$ perl6 -v
This compiler is built with the Parrot Compiler Toolkit, parrot revision 45822.

但是我怎么知道rakudo 版本，avx.xx还是{some-git-hash}？

谢谢，

Answer 1

Currently you can't know :(

There's a patch for that in RT that awaits review: http://rt.perl.org/rt3/Ticket/Display.html?id=73148 but so far it hasn't been applied yet.

Update: With a sufficiently new Rakudo, you get:

$ perl6 -v

This is Rakudo Perl 6, version 2010.06-212-g1086ff8

Where the thing after "version" is the git describe output.

perl6 -v 现在可以工作了。它提供了上一个月度发布、自那时以来的提交次数以及 git 哈希。
